Stromata amphigenous but more frequently epiphyllous, forming dark brown to black, 
orbicular spots up to 2-4 mm. diam. These are usually quite distinctly radiate and 
fibrillar in structure, even to the naked eye. 
The hypostroma may be detected within the leaf, lying between the epidermis and 
the palisade cells, and pushing down between the latter. In the #laeodendron spp. there 
is more than one row of epidermal cells; but even then the internal mycelium penetrates 
between all the rows of cells as far as the palisade tissue. At certain points the hypo- 
stroma becomes much thickened and a hyphal mass is produced above the palisade cells 
which gives rise to a short, dark, cylindrical column of perpendicular prosenchymatous 
structure. This column or foot ruptures the epidermis and the hyphae composing it 
flatten out horizontally and form the stroma; certain of the hyphae form a hypothecium 
about 10 vu thick, and others growing to a higher level produce the radial covering 
membrane. The illustration of the stroma of Asterodothis solaris in the Annales Myco- 
logici [13 (1915), Tafel I, Fig. 10] is somewhat misleading, as it depicts the loculi in close 
contact with the central column. This is not always the case, as in the large number of 
sections examined of the fungus on various hosts the central part of the stroma was 
sterile and the loculi were at some little distance, closely crowded, forming a sort of crown 
round central point or being irregularly scattered about the centre. 
The central part of the stroma as seen in a surface section may be parenchymatous 
in structure, in which case the loculi show as small mounds; but frequently the locul 
appear as dense black bodies borne on radiating hyphal strands which are more or less 
connected with one another. The loculi (external measurement) are round 200-250 u 
diam., or oval, 250-300 u x 140-200 u; they dehisce irregularly by a stellate or longi- 
tudinal fissure. 
In section the loculi are 120-160 » high, and are connected with the intramatrical 
hypostroma by numerous dark coloured fungus pegs which pass through the stromata. 
This fact is not mentioned by Theissen. 
Radiating from the stroma are numerous hyphae which are almost straight, dark brown, 
septate, 5-6 u thick; these often become adnate by their radial walls and form hyphal 
strands. The hyphae produce branches, which form acute angles with the parent hypha. 
On the hyphae are borne numerous outgrowths which may be regarded as rudimentary 
setae or bristles. These are sometimes very short and almost like hyphopodia in appear- 
ance; more frequently they are more or less erect, truncate, and up to 254 x 7-8 uy. 
On the hyphae are also borne very dark brown, club-shaped conidia, which are 3-4 septate, 
blunt at the ends, and 36-42 u x 11-12 u. 
The fruiting layer is flat and the asci parallel, oval to clavate, eight-spored, 70-90 u x 
24-28 vu. Paraphyses numerous, filiform. Spores distichous, ellipsoid, reddish-brown, 
smooth, 27-31 u long, upper cell 10-12 u broad, lower cell 8-10 u broad. 
The spores have a peculiar method of germination, the germ tubes appearing on the 
medial constriction between the two loculi, one on each side. 
A fungus with a similar conidia to Asterodothis solaris has been collected on Myrsine 
melanophleos [10908] and [8995], but unfortunately neither of these two collections bear 
mature ascostromata.
